Another great look for keeping costs low and keeping the occasion magical. The canopy of lights is achieved by using long white corded strands of mini-lights, similar to Christmas tree lighting.
A gentle swoop over the long table hugs the guests as they feast in celebration. With nary a flower in sight, this table design is focused on good conversation over glitz and showmanship. This is a true lesson in keeping things simple: white gauzy runner, candlelit lanterns, and plain tableware.

With the exception of the white cotton lace table runner, you can find all the glassware and similar centerpieces at Ikea. I was just there over the weekend and found tons of great vessels for entertaining.
